200 Quattro Avant rear suspension

[mark schofield]

I need to replace some worn parts on the rear suspension of a 1987 200
Quattro Avant and have been a bit horrified at the cost. The transverse
links are £170 each and the rubber bush in the trapezoidal arm £54. That's
almost £500 for two bushes and a couple of track rods.
These are VAG prices, I am assured by an independent Quattro specialist that
they aren't available from any other source.
Any lister BTDT or located these parts elsewhere?
Thanks
Mark
